STIRRU P.

SPECIFICATION forming part of Letters Patent No. 445,411, dated January 2'7, 1891.

Application filed October 29,1390. Serial No. 369,740. (No model.)

To all whom it may concern.-

Be it known that we, NELs PEARSON, a citizen of the United States, and SVEN OLssoN, a subject of the King of Sweden, both residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Stirrups, which improvement is fully set forth in the following specification and accompanying drawings.

Our invention consists of a stirrup having the foot portion adapted to overturn when the rider is thrown, and in providing said portion with a guard which is adapted to be separated, whereby thefoot may be readily cleared of the stirrup, as will be hereinafter set forth.

Figure 1 represents a perspective view of a stirrup embodying our invention. Fig. 2 represents a partial elevation and partial sec tional View thereof.

Similar letters of reference indicate corresponding parts in the two figures.

Referring to the drawings, A designates the side pieces, frame, or bow of a stirrup, to which is pivoted the foot or base part B. Secured to or formed with said part B and projecting inwardly from the sides thereof are ears C, to which are pivoted the arms D, which when in their normal position are within the bow A of the stirrup proper. The lower ends of the arms bear against plugs E, which are freely fitted in a tube F, the latter extending from side to side of the base-piece B and secured thereto. which bears against the plugs E, whereby the upper ends of the arms D are held in contact and closed, presenting the appearance of a bow smaller, of course, than the bow A.

The operation is as follows: The foot. is

\Vithin said tube is a spring G,

placed on the base B and within the bow or arms D, the stirrup then rendering service as usual, the arms acting as a guard, preventing the foot from engaging or entangling with the bow A. Should the rider be thrown from the animal and his foot remains in the stirrup, the base turns or overturns, as shown in Fig. 2, and the pressure on the foot against the arms separates the latter, as shown by the dotted lines in said figure, whereby the foot clears said arms, and is thus entirely disengaged. from the stirrup. The arms then close, and the base, with its connect-ed parts, may be restored to its normal position, as in Fig. 1.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. A stirrup having a base provided with movable guard-arms and a closing-spring bearing against the same, said base being piv; oted to the bow and said arms being primarily located within said how in closed condition and adapted to open when the base overt-urns, thus releasing the foot, substantially as described.

2. A-stirrup consisting of a frame with pivoted basepiece, ears projecting from said frame, arms pivoted to said cars, a tube secured to said base-piece and having a spring therein, and plugs freely fitted in said tube and held by the action of said spring against said arms, said parts being combined substantially as described.
